Understanding the near-threshold structures in $$e^+e^-$$ annihilation from a unified $$N\bar{N}$$-interaction perspective

Abstract Near-threshold structures have been observed in the cross sections for $$e^+e^-\rightarrow p\bar{p}$$ e + e - → p p ¯ , $$e^+e^-\rightarrow n\bar{n}$$ e + e - → n n ¯ , and several non-baryonic final states in the vicinity of the $$N\bar{N}$$ N N ¯ thresholds. We investi...
